面向实车应用的锂离子电池系统温度采集技术
摘要：摘要电池模块的温度采集准确性是影响电池管理系统（BMS）控制策略,关系到动力电池安全和寿命的重要因素。为准确采集锂离子电池在实车应用过程中的温度,设计一个2P8S电池模块,选取模块的两个电芯,在其不同部位及其对应的高压铝排上布置温度传感器。通过搭建实验平台,将电池模块分别放置于25 ℃和0 ℃的环境温度,对电池模块运行整车常用工况电流,研究各温度采集点的温升表现和规律。结果表明,对于方壳电芯和圆柱电芯,温度传感器布置在高压铝排上是相对最优解。对于软包电芯,温度传感器布置在电芯本体表面更为合适。
Abstract:：The accuracy of temperature collection in battery modules is an important factor affecting the control strategy of battery management system (BMS), which is related to the safety and lifespan of power batteries. To collect the temperature of lithium-ion batteries more accurately during actual vehicle applications, this study designs a 2P8S battery module, selects two cells of the module, and arranges temperature sensors on different parts and corresponding high-voltage aluminum bars. By building an experimental platform and placing the battery modules at ambient temperatures of 25 ℃ and 0 ℃, the temperature rise performance and patterns of each temperature collection point were investigated under the common operating current for vehicle operation of battery modules. The final experiment proved that placing temperature sensors on high-voltage aluminum bars is a relatively optimal solution for square shell cells and cylindrical cells. For flexible battery cells, temperature sensors are more suitable to be placed on the surface of the battery cell body.
